The geometrical branching model with jets is used to analyze the data on sigma/sub el/,sigma/sub tot/,, and the higher moments of particle multiplicity in hadron-hadron collisions at all available energies. The eikonal formalism is used as the framework to combine the soft and hard components of the multiparticle production process. The soft component of the eikonal function is assumed to be geometrical scaling even in the presence of the hard component. We show in the context of the model that the geometrical size of a hadron ceases to increase in the energy region of the CERN Spp-barS collider. The production of jets is shown to be responsible not only for the continued increase of the inelastic cross section, but also for the breaking of the Koba-Nielson-Olesen scaling.
